Insects. 3251 



inferred that the female does not construct her own burrow; the males 

 which I observed might have been re-opening a burrow accidentally 

 closed : but every incident, " meet it is I set it down." This insect 

 was observed by Latreille to provision its nest with Apis mellifica ; 

 thus we see, that like other Hymenoptera, when one species is not at 

 hand, it selects some other which equally well answers its purpose. 

 Thus, Larra pompiliformis at one time chooses a lepidopterous larva, 

 and at another, as I have formerly shown, a grasshopper answers its 

 purpose. 



Of the Diplopteryga I observed only the two following species : — 



Odynerus parietum. This species was in great profusion, and the 

 majority of them were infested with the larvae of Meloe ; off one spe- 

 cimen I picked twenty-four larvae ; they adhere to the coxae and rae- 

 tathorax of the wasps. I captured a considerable number of these 

 wasps, and was astonished at the immense number of larvae found on 

 them ; indeed, most of the bees were infested with them, particularly 

 Nomadae. 



Odynerus spinipes. Very numerous, although rather late for the 

 insect. 



Colletes fodiens and Daviesana. The latter in profusion. 



Sphecodes gibbus and Georrroyellus. 



Prosopis hyalinatus. In the greatest profusion. 



Halictus rubicundus {male), H. Smeathmanellus (very plentiful), 

 H. villosulus, H. minutus. 



Andrena fulvicrus. 



„ simillima, Smith. Of this new and beautiful species I cap- 

 tured a single female at Luccombe landslip ; since which Mr. Baly 

 has met with both sexes at Folkstone. I have described the species 

 in the c Museum Catalogue of British Aculeate Hymenoptera.' 



„ thoracica. This species was plentiful, and was the only 

 bee which I observed to frequent the everlasting pea (Lathyras syl- 

 vestris), which grows at Shanklin, and also at Luccombe, in the most 

 wild and beautiful luxuriance. 



„ chrysoceles, A. xanthura. 



„ ? New species ; male. 



Cilissa tricincta. 



Panurgus calcaratus. This local little bee I found in plenty at Luc- 

 combe Chine. 



Nomada varia. Very abundant. I was delighted to meet with this 

 beautiful little bee again ; I only once before met with it in any num- 

 bers, that was in a lane leading from Green-street-green to Betsomc,
